[SOLVED] Adding MTA

Hello.

I'm looking at adding an MTA to my current Zimbra install to help move the external email processing off the mailbox store/web interface.
Right now the main Zimbra server is running Zimbra 4.0.5 on RHEL 4.
I know I'm going to want to setup the MTA with exact same version of Zimbra.
I was wondering if it would be fine if I installed that on RHEL 5 or if I would need to install it on RHEL 4 as well?

As long as MTA (Zimbra) version i Zimbra 4.0.5..OS version dont matter.
although..
i suggest you update Zimbra to latest version 5.0.1x first and use the same version on MTA (useing RHEL 4 or 5 dont matter)
